On Sunday, December 29, the 44-year-old reality TV star posted an Instagram carousel of pictures with her children from Christmas Eve. Kardashian shares her four kids with ex-husband Kanye West: daughters North, 11, and Chicago, 6, and sons Saint, 9, and Psalm, 5.

The new hair length is only the latest in a series of dramatic transformations for the SKIMS founder throughout the holiday season. At the company’s Christmas party in Los Angeles on Dec. 19, the mogul sported a ’90s-era hairstyle, complete with high volume, large waves and swooping bangs — which she paired with a form-fitting red leather gown.

Kardashian wore a red spaghetti-strap gown and smiled next to daughter North, 11, who nearly stood taller than her mom in black mini shorts, a white corset top with a black cropped tie and matching blazer. In front of the mother-daughter pair were son Psalm, 5, daughter Chicago, 6, and son Saint, 9.
